LOADING-MACHINE.

Specification of Letters Patent. Pgyfiygntedl App, 1Q), 1%]1},

Application filed May 17, 1915. Serial No. 28,6l 8.

To all whom it may camera:

Be it known that I, CHAnLns F. FIFIELD, a citizen of the United States, residing at Hastings, Michigan, have'invented certain new and useful Improvements in Loading- Machines, of which the following is a specification.

This invention relates to improvements in loading machines.

My improved loading machine is espeeially designed by me for loading gravel, sand, crushed stone or coal or the like from piles or embankments, although certain features thereof may be readily adapted for use in other relations. I

The main objects of this invention are:

First, to provide an improved loading machine adapted to load gravel, sand, crushed stone, coal or the like from piles or embankments without the necessity of shoveling the material to the machine. 1

Second, to provide an improved loading machine having these advantages which is of large capacity.

Third, to provide an improved loadin machine which is comparatively simple an economical in structure and very easy to operate.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a side elevation of my improved loading machine.

Fig. II is a rear view thereof.

Fig. III is a horizontal section on a line corresponding to line 33 of Fig. I.

Fig. IV is an enlarged detail vertical section through the elevator frame swivel on a line corresponding to line 44 of Fig. II.

Fig. V is an enlarged detail view, partially in section, on a line corresponding to line 5*5 of Fig. III.

Fig. VI is a detail vertical section through the delivery chute on a line corresponding to line 66 of Fig. II.

Fig. .VIII is a detail horizontal section through one of the elevator frame carrying wheels showing the locking means therefor.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is designed to be operated on a track 1. members formed of longitudinal sills 2 disposed in a spaced relation to receive the truck wheels 3 between them. The outer or rear side member is longer than the front or inner side member, as clearly shown in Fig. III.

The outer wheels 3 are arranged at the ends of the outer side member while the inner wheels 3 are arranged in a spaced relation to the ends of the inner side member.

The side members are connected by cross pieces 4., the cross pieces being connected to the inner side member on the outer sides of the truck wheels and to the outer side member on the inner sides of the truck wheels.

The axles 55, 6 and 7 are carried by the bearing hangers 8 arranged on the under sides of the side member sills. The axle 6 has an extension 6 extending to the outer side member and supported by a bearing 6 thereon.

The axle 7 has an extension 7 projecting at the inside of the outer side member.

The axle extension 6 is provided with a sprocket wheel 9 while the axle extension 7 is provided with sprocket wheels 10 and 11. The sprocket wheels 9 and 10 are connected by the sprocket chain 12.

A. driving shaft 13 is carried by a bracketlike arm 14 on the outer side member. This driving shaft is provided with a hand wheel 15 and with a sprocket wheel 16, the sprocket wheel 16 being connected to the sprocket 11 by means of the sprocket chain 17. With the parts thus arranged the truck may be driven or moved along the track to feed the conveyor into the bank or pile.

The elevator frame comprises the elevator side bars 18 which are mounted on the front ends of the horizontal sills 19 and the upper ends of the uprights 20, the uprights being mounted on the rear ends of the sills 19. The frame is braced by the horizontal braces 21 extending between the uprights and the elevator side bars 18 and the upright The truck frame comprises side braces 22 extending between the sills 19 and the side bars.

A pan or shield 23 is arranged above the engine and gearing. This pan is inclined so that the material dropping thereon runs off.

The elevator frame is provided with a swivel pin 24 which is carried by the bearing member 25 resting upon the bearing block 26 secured between the sills of the outer side member. The bearing member 25 is carried by a cross piece 27 at the rear ends of the horizontal sills 19. The swivel bearing member 26 is arranged at the axial center of the segmental track 28 which is mounted on the truck frame above the truck wheels, see Fig. II.

The elevator frame is provided with carrying wheels 29 mounted by means of brackets 30 on the sides of the horizontal sills 19 so that the wheels travel on the track 28.

The engine 31, shown conventionally, is mounted on the cross piece 32 carried by the horizontal sills so that it is substantially above the swivel for the elevator frame and assists in counter balancing the frame.

The elevator buckets 33 are carried by a chain 34 mounted on the sprocket wheels 35 and 36 at the top and bottom respectively of the side bars 18.

The shaft 37 for the sprocket wheel 35 is arranged at the lower ends of the side bars so that the buckets are filled as they sweep around the sprocket wheel 35. The shaft 38 for the upper sprocket wheel 36 is provided with a sprocket 39 connected by the sprocket chain 40 to a sprocket 41 on the transmission shaft 42 carried by the bearings 43 on the horizontal sills 19.

The shaft 42 is connected by the gears 44 and 45 to the transmission shaft 46 on which are tight and loose pulleys 47 and 48 for the engine belt 49. This provides a simple and effective driving connection for the en gine to the conveyer.

The conveyer chain 34 is supported by the rollers 50 arranged at intervals on the side conveyer side bars, see Fig. I.

To retain the elevator frame in its adjusted position on its track I provide a lock for.

one of the wheels 29, the lock consisting of a pin 51 adapted to reciprocate in a suitable hole in the bracket 30 and engage holes 52 in the wheel, see Fig. VII. The pin is re tracted and projected by means of the lever 53 which is pivoted at 54 and slotted at 55 to engage the pin. This effectively holds the elevator and at the same time allows it to swing on the track in the event of the shovels striking a stone or other obstruction which might injure the machine if the elevator were more rigidly secured.

In practice the track is laid so that the truck is moved along the track to feed the elevator into the embankment. In the accompanying drawing I have shown the elevator positioned at right angles to the track. In ordinary practice it is swung forward so that as the truck is fed along the track the buckets are brought into proper position to effectively take up the material.

7 The machine illustrated is especially designed for delivering into wagons and I provide a chute 56 to which the buckets deliver, the chute having a screen 57. The chute is supported by a brace 58 and is provided with a pivoted spout portion 59 which may be raised and lowered by means of the rope 60 arranged over a roller at 61 and secured at 62. A guard 63 is arranged below the screen, the upper end of the guard being pivoted at 64 and its lower end supported by the rope 65 connected to the rope 60, as shown in Fig. I. With this connection of parts the spout and the shield may both be raised at the same time to permit a wagon being driven under the spout.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a structure of the class described, the combination of truck frame side members, the outer side member being longer than the inner, wheels mounted on said side members, the distance between theouter wheels being substantially greater than the distance between the wheels on the inner side member, axles for said wheels mounted on said side member sills, a segmental track disposed upon said side members above said wheels, a super frame swiveled on said outer side member, wheels on said super frame traveling on said track, and a lock for said super frame.
